BitWise
Wire circuits by hand, from a lamp and battery up to a stored-program machine
BitWise is a puzzle game about building circuits by hand. You place parts on a bench, wire them, and the circuit runs on a real simulator, with analog parts solved the same way SPICE does it. The grader only checks what the circuit does, so any working build passes. Parts you make, such as an XOR built from NAND gates, become chips you reuse later, up to an ALU and a machine that runs a stored program.
